Abstract

a presente invenção se refere a uma disposição de mancal (1) para um cabeçote de perfuração por líquido de lavagem de um equipamento de perfuração profunda com vários anéis de mancal radialmente exteriores e radialmente interiores (6, 7), na qual os anéis de mancal radialmente exteriores (6) estão dispostos coaxialmente sobre os anéis de mancal radialmente interiores (7), na qual radialmente entre os anéis de mancal (6) estão dispostas esferas (8), as quais rolam em estrias de rolamento (6a, 7a) dos anéis de mancal (6, 7), e na qual as estrias de rolamento (6a, 7a) axialmente nos dois lados de ressaltos (6b, 7b) estão delimitadas com superfícies de ressalto (6c, 7c) situadas opostas uma à outra, que passam paralelas a um eixo longitudinal do mancal (11). a fim de executar uma disposição de mancal (1) desse tipo à qual se conecta o, pelo menos um, mancal plano na direção axial de acordo com o estado da técnica curta na extensão axial e a fim de simplificar a construção, o diâmetro interno (di) das superfícies de ressalto (6c, 7c) dos anéis de mancal radialmente exteriores (6) e o diâmetro externo (da) das superfícies de ressalto (7c) dos anéis de mancal radialmente interiores (7) é dimensionado de tal modo que essas superfícies de ressalto (6c, 7c) realizam a função de mancais planos radiais com uma folga radial (s).The present invention relates to a bearing arrangement (1) for a scrubber drilling head of a radially outer and radially inwardly deep bearing ring (6, 7) in which the bearing rings radially outer bearings (6) are arranged coaxially over the radially inner bearing rings (7), in which radially between the bearing rings (6) are disposed spheres (8) which roll into bearing grooves (6a, 7a) of the bearing rings (6, 7), and in which the bearing grooves (6a, 7a) axially on both shoulder sides (6b, 7b) are delimited with shoulder surfaces (6c, 7c) opposite each other, which run parallel to a longitudinal axis of the bearing (11). in order to perform such a bearing arrangement (1) to which at least one axial direction plain bearing is connected according to the state of the art in short axial extension and in order to simplify construction, the inner diameter (di) of the shoulder surfaces (6c, 7c) of the radially outer bearing rings (6) and the outside diameter (da) of the shoulder surfaces (7c) of the radially inner bearing rings (7) is dimensioned such that These shoulder surfaces (6c, 7c) perform the function of radial plain bearings with radial clearance (s).
